Serial Management Controllers (SMCs)
To use the SMC GCI channels properly, the TSA in the SI must be configured to route the
monitor and C/I channels to the desired SMC. See 7.8 Serial Interface with Time Slot
Assigner for more details on how to program this configuration. The following SMC discus-
sion assumes that this time-slot routing is programmed properly.
7.11.14.1 SMC GCI MEMORY MAP. The GCI parameter RAM area begins at the same off-
set from each SMC base area.
The SMC GCI mode has a very different set of parameter RAM than the SMC UART or SMC
transparent modes. In the SMC GCI mode, the general-purpose parameter RAM contains
the BDs, rather than pointers to the BDs. Contrast Table 7-15 with Table 7-12 to see these
differences. Additionally, the SMC in GCI mode contains no protocol-specific parameter
RAM.
7.11.14.1.1 SMC Monitor Channel Transmission. The monitor channel 0 is used for data
exchange with a layer 1 device (e.g., reading and writing internal registers and transferring
of the S and Q bits). The monitor channel 1 is used for programming and controlling voice/
data modules such as CODECs.

NOTES:
RSTATE, M_RxD, M_TxD, CI_RxD, and CI_TxD do not need to be accessed by the user in normal
operation, and are reserved areas for RISC use only.
The SMCs on the QUICC differ from the SMCs on the MC68302.
On the QUICC, a single SMC handles both the monitor and C/I
fields of a GCI channel. On the MC68302, one SMC handles the
monitor field, and another SMC is required for the C/I field. Ad-
ditionally, the MC68302 cannot use SCIT channel 1; whereas,
the QUICC can.
